Here’s a short clip showing a nice little metronome app by Knowledge Rocks, the MyBeat Metronome. I’ve used a few different metronome apps on my iPhone over the last few years and this is one of the most straightforward to operate.
The best thing about this for me is the ability to ‘shake in’ tempos – I’d always used tap tempo as a means of getting an accurate bpm for transcriptions or when working out tempos during rehearsals but this allows me to physically ‘get in’ to a tempo and feels a lot more natural than repeatedly tapping a screen.
